The convertible BugsAway® Ziwa is a true sporting pant, with a quick-drying, UPF 30 fabric. A partial elastic waist moves with you, and when your legs cry out for a breeze, change to a 10" short by zipping off the legs; roll them up and stuff them away in the two side cargo pockets. About BugsAway®: BugsAway® apparel is treated with Insect Shield®, giving you invisible, odorless protection just by putting on your clothes. The treatment is bound to fabric fibers, so it stays in your clothes-not on your skin-and lasts through 70 washes. Ants, flies, chiggers, midges, and ticks don't like it, and neither do mosquitoes, which can transmit insect-borne diseases such as Zika, Chikungunya, dengue, and West Nile viruses.
